Application filed August 8, 1925. Serial No. 48,990

i '0 all whom it may concern:

Be it known that I, FREDERICK FRANCIS Fnorrnn. a citizen of the United StateS, and a resident of Rockville Center, in the county of Nassau and State of New. York, have invented certain new and useful Improvements in Duplicators, of which the following is a specification.

The invention relates to duplicators, more particularly to that form of duplicator in which a. negative or reversed impression of matter to be copied is impressed upon an various devices, elements and parts, as set forth in the claims hereof, one embodiment of the same being lllustrated 1n the accompanying drawings and described in this specification.

In the said drawings,

Fig. 1 is a perspective view of one embodiment of my invention;

Fig. 2 is a plan view thereof, the swinging paper-holding device being removed; and

Figs. 3 and 4 are fragmentary side views showing the paper-stripping mechanism in ditli'erent positions.

in carrying my invention into effect in the embodiment thereof which I haveselected for illustration in the accompanying drawings and description in this specification, I provide a main frame structure of any form suitable for the purpose, such as may comprise a base having mounted thereon frame members 12, suitably connected together so as to make a frame of suiticiently rigid construction.' A bed 16, secured between said frame members, corn prises or serves a suppe t for a adhesive duplicating surface 14. This adhesive duplicating surface may be either the surface of the bed itself,or a portion of a film or strip secured to the bed, or there may if'desired be acomparatively long sheet the portions of which not in use may be stored upon rollers journaled between said, frame iembers, according to a construction which is well understood in the art to which said duplicators' relate. the means for the storage of the. film and for win-ding and unwinding same therefromand passing same over the support,as the bed 16, form no part of the present invention, it is not necessary to describe the same in detail.

Adapted to co-operate with the devices above referred to, I provide an attachment comprising a paper-support or' table member, which is preferably in the form'of a shallow tray, having a bottom 23 covering the entire area with the exception of an opening at one end, as will-be seen in Fig. 1. The tray may be provided with side and end walls 21 and with a. paper-repressing member 80 which lies over the opening 20 in the floor of the tray, the function of which is to operate, when depressed, to bring the lowermost sheet of paper into contact with the adhesive duplicating surface. This paper-depressing member is mounted upon a shaft 31, and springs 32 maybe provided, tending to keep the member normally out of contact with the paper.

The tray is provided with a handle 33 for convenience in operating the same, and with a hook 35 adapted to engage with a stud 36 in one of the side frames, for the purpose of holding the tray in its lowered position when not in use. The tray is pivotally supported on the frame by meansof lugs 37 which engage with a rod 38, the spiral spring 39 tendingto hold the paper-tray in the ele vated position shown in Fig. 1.

At the right-hand side of the machine is a rod 40, the ends: of which are secured in brackets 41 in one of the side frames of the machine.

Mounted on the rod is a slidingn'iemher it havinga laterally extending frame 15' in which, is j' realed a r ller 46. This frame is also provided with a handle t? for convenience in operating the same. Also mounted on the rod is a second sliding member having a laterally extending frame 51 in which is journaled a roller Secured to the sliding member 44; is a pivoted latch 55 which is adapted to engage with a stud 56 on me second sliding member 50 and thereby couple the two sliding members together when desired. A spring 57 tends to depress the latch 55 into engagement with such stud On the side frame 12 is a stop 60, adapted when the sliding members are moved up to the same, to elevate the latch 55 and disengage itfrom the stud 56. Near the other end of the side frame is a casing 61 in which a coiled spring to which is secured a cord 62 secured to the sliding member 56, and tending to draw the same baelt along the rod 40 when disengaged from the sliding member 44-. An adjustable step 63 may be so: at any desired point upon the rod 410 to prevent the sliding members from pas. lng too far back.

65 represents a sheet of paper, most of which is lying flat upon the adhesive duplicating surface but one end of which, indieated at 66, is shown raised up above the adhesive duplicating surface and passing between the rollers 46 and 52.

The operation of the above described embodiment of my invention is as follows: Upon the paper-supporting device is placed, face downward, a sheet of paper bearing the matter which it is desired to copy, the same being written or printed with so-called heetographing ink, and upon this original may be placed any number sheets of blank paper upon which it is desired to copy the matter transferred from the original to the adhesive duplicating surface. If it is desired to position said sheets of paper at any particular place upon the paper-supporting device, adjustable side and end steps may be employed, which, however. form no part of the present invention. It will be nderstood that the ends of the sheet of paper must always lie over the opening in the floor of the paper-supporting member, and that after the paper is placed in position the paper-depressing member 30 is swung down into position over the ends of the sheets of paper. The original and blank sheets of paper being thus in place upon the paper-supporting member, the pile of paper may if desired be steadied by placing the hand upon the same, although ordinarily this will not be necessary, and the same depressed so that it comes down upon the machine. The paper-depressing member 30 is then operated, which forces a portion of the pap r, or if there are a number of sheets of paper on the tray, :1 portion of the lowermost sheet, down upon the adhesive duplieating surface, to which it adheres. In the embodiment of the invention which is now being described, the lowermost sheet of paper will be the original containing the matter desired to be transferred to the adhesive duplicating surface. The tray is then elevated, and as the paper is held by the adhesive duplicating surface it is drawn out from under the other sheets of paper and lies fiat upon the adhesive dupl'cating surface, except that the back end of the sheet, shown at 66 in Fig. 1, is prevented from falling upon the adhesive duplicating surface by means of the roller 52. The sliding frame 44: at the time of lowering the papertray and depositing the sheet of paper, is toward the front of the machine, and the sliding frame 50 at the back of the machine, both as shown in Fig. 4:, but as soon as the paper has been laid upon the adhesive duplicating surface, the frame carrying the roller 46 is moved ackward into the position shown in Fig. 1, the roller serving to depress the paper firmly upon the adhesive duplicating surface. lVhen the same reaches the position shown in Fig. 1, the latch engages with the pin 56 on the frame 50. thus locking the two members together and holding the upturned edge 66 of the paper between the rollers 46 and 52. The sliding members are then drawn forward ly means of the handle 47, the operator meanwhile holding the edge of the paper 66 and drawing it gently upwards as the forward movement of the rollers between which the paper lies strips the same from the adhesive duplicating surface. Upon the sliding frames reaching the forward end of the machine, the paper is entirely disengaged from the adhesive duplicating surface and is removed by the operator, and the latch 55, coming in contact with the stop 60, is dis engaged from the sliding frame 50, where upon the latter is drawn backward by the spring 61 which winds up the cord 62. The roller 52 being then in its lachward position, and the roller 46 in its forward position, the adhesive duplicating surface is ready to receive another sheet of paper,

which is deposited thereon as before, the frame 4:4 pushed back ard, and the whole operation above described repeated as many times as may be desired.

\Vhen the machine is not in use, the paper-tray may if desired be held downward in a safe position by means of the hook 35 and stud 36.

I do not limit myself to the particular form of construction and combination of parts which I have above described and shown-in the accompanying drawings, as it is oliivious that many changes in detail can be made without departing from the spirit and scope of the invention.

I do not limit myself to a form of construction in which the paper-supporting lUO lll)

member is pivotally mounted so as to swing in a v rtical plane over the other parts of the m chanism. I consider such a construction preferable, but it is obvious that the paper-sruaportiing member might be otherwise swingingly mounted, or slidably mounted, the function and operation of the same remaining substantially as above described.

The advantages of my invention will be obvious from what has been above said with regard to its construction and method of operation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is as follows:
